Freedom of association is very link with the freedom of speech. College students at Government run colleges need to get use to the real world. They ( or the administration) cannot just engage in rampant viewpoint discrimination or try to cut off at the head groups and opinions they do not like. That is , at least currently , not how life in the real world operates.

This has wider implications than just the college campus. Trying to dictate membership and leadership requirements, overreaching vague speech and conduct codes, and often kangaroo campus " courts" teach students a horrible lesson. Harvey Silverglate pointed this recently in this Forbes article Campus Censorship Breeds Societal Dysfunction where he reviews an excellent and alarming book on this topic.

Unlearning Liberty gave me surprising insight into how it could be that such a large number of graduates of some of the nation’s leading colleges and law schools wind up as U.S. Department of Justice prosecutors doing so many awful things to so many often innocent people. I likewise gained insight into how some of the sharper legal minds now sitting on the federal bench do not blanch when innocent citizens are convicted of violating statutes and regulations that no normal person could possibly understand.

Amen to that. All these things are connected. That is sometimes in the noble aim of "tolerance" we decree by law or regulation in toleration.
